Air density
Engine cubic capacity
Engine speed
O Clearance volume​

Answer 1

Answer:

c options because all the pole in the mud

Answer 2

Clearance volume does not affect the volumetric efficiency.

Explanation:

• Volumetric efficiency of an engine is referred as the degree of completeness with which the engine cylinder is filled with fresh air during suction stroke.
• Some common factors that affect an engine's volumetric efficiency are intake and exhaust restrictions, valve timing, cylinder sealing, gas inertia, runner design and rpm, among others.
• Some external factors affecting VE are barometric pressure, air temperature and humidity.
• Hence, the correct answer is option (d) Clearance volume.
